Hello all,
Just in case there are still questions about accessing object storage, attached/below is a basic script to illustrate how to do the basic operations using curl. It is not fancy...but might give you ideas for your development.
It was tested on Ubuntu 13.04 with curl installed.
It is configured for fi-lab...just put in a fi-lab username and password.
The script:
- Gets initial token, then tenantId, then token for that tenantId
- Creates container
- Stores / reads some basic text. Deletes the file.
- Stores / retrieves a data file (the dat file in attached is actually a jpg file). Deletes the file
- Deletes the container.
I will try to clean it up further on Monday and embed a version of it with the online documentation for support purposes.
In case some email firewall blocks the attachment there are two files:
- CDMI_object_test_data.dat is a file with any data in it. My example has a jpg picture in it.
- Cdmi_example_filab.sh - this is the script pasted below.
Rgds,
- John.

#
# Simple script to show some accesses to CDMI on devstack using curl
#
# Basic flow is :
# Retrieve token
# Check container 'capabilities'
# Create a container, check it
# Put an object in the container, read it, delete it - simple data
# Put an object in the container, read it, delete it - user supplied data file
# Delete the container
#
# There are some pauses in case the user wants to check container using the web
# portal
